How do I know if my shower head has a flow restrictor?
Flow restrictors are usually found in the neck or threaded end of the shower head exposed when the shower head is removed from the shower arm as shown in the image below. They would appear in the opening of the aerator when it is removed from a lavatory or kitchen faucet.
The National Energy Act requires that shower head manufacturers install a flow restrictor or flow controller in shower heads.
What does a flow restrictor look like? Before you remove the flow restrictor from your shower head, you need to know what it looks like. A water flow restrictor is usually a flat, circular, plastic piece. The center of the restrictor is shaped like a star, or similarly shaped, and comes in a variety of colors.
Removing the water restrictor from your showerhead can also improve water pressure. Removal might also clear out mineral build-up around the restrictor.
By managing water flow, a flow restrictor prevents built-up pressure from damaging pipes, appliances, and fixtures. Not only do flow regulators save you money by decreasing damage to appliances, but they also save water in lines with high pressure.
Most low-flow showerheads have a rubber pressure-reducing valve (called a regulator) to maintain a lower pressure. You can increase the flow by simply taking it out. You could also consider enlarging the hole that allows water into your showerhead with a drill to increase the amount of water coming through.
Low pressure in a shower can be caused by several issues such as a clogged showerhead, a worn-out mixing valve, closed valve, leaking pipe, or even a faulty water heater.
The flow restrictor is not removable but easily drillable. Use a 1/4" drill and go right through it. Go easy as you want it to come out with the drill. 1/4 is the max size you can use as the metal retaining the plastic restrictor is that size.
The screw is your adjuster and it can be maneuvered only by loosening the locknut. As you tighten the screw, the water pressure will become greater and as you loosen it, the water pressure will lessen, so turn the screw clockwise to increase the pressure, or turn it counterclockwise to decrease the pressure.
The flow restrictor is usually blue or green, sets inside the fixture, and is easy to access. Often times it has a couple of tabs that can be grabbed with a pair of needle-nose pliers.
How do I stop shower water from escaping?
- Showerheads that point downwards. ...
- Correctly Sized Shower Screens. ...
- Low profile floor tiles. ...
- Install a higher flow drain than needed. ...
- Consider a pivoting glass door.
Turn off the water supply. Unless you happen to have a separate cutoff valve installed in the bathroom, shut off the water to the whole house. Open up a faucet at a lower level in your home to relieve pressure in the lines and leave it open as you work.

Flow restrictors on a kitchen faucet are small disk-shaped barriers that reduce the amount of water that comes out the faucet. They are installed in various configurations, and may be either added as a unit that replaces the conventional flow-directing screen on a faucet, or built in as part of the faucet itself.
Results from low flow, or flow restricted, shower heads and flow restrictors will vary, but you could reduce consumption by up to 60%.
Please keep in mind that all new faucets since 1994 are restricted to conserve water per EPA code mandates. Older faucets had no restrictions.
Also known as "flow rate", GPM is a measure of how many gallons of water flow out of your shower head each minute. Since 1992, a maximum of 2.5 GPM is the federally mandated flow rate for new shower heads. This means no more than 2.5 gallons of water should flow out each minute.
Without a water pressure regulator, your RV's plumbing could spring a leak! Without a pressure regulator as protection, excessive water pressure may be allowed to run into your RV's plumbing system, risking damage to seals, fittings, and the plastic “PEX” pipes running throughout your RV.
The most common causes of high water pressure include: High supply pressure – In areas where there are tall buildings, fire hydrants, or plenty of hills, the pressure of the municipal water system may be set intentionally high to ensure adequate pressure at all locations.
Are there shower heads that increase water pressure? Yes. High-pressure shower heads increase water pressure either by decreasing the flow rate or using a compression chamber.
Because they're so much bigger than the average showerhead, but still provide the same amount of water (which can vary by water-saving mandate depending on where you live), it's just math: The same amount of water delivered across a bigger surface = less pressure. That's not the only drawback.
Where is my water pressure regulator?
A water pressure regulator, if you have one, is usually located where the main water line comes into the house and after the main shut off valve. This way if you need to work on or change the water pressure regulator you can simply shut off the water main to do so.
If you notice low water pressure from just one or two of the fixtures in your house, the problem likely has to do with debris buildup. Water is full of minerals and other debris, all of which can accumulate in your pipes and on your fixtures. This can cause a blockage that affects how much water flows through.
A water pressure regulator is a dome-shaped brass fitting that generally is found just past the main shutoff valve, where the main water line enters the house. It usually has an adjustment screw on top.
When to Change the Flow Restrictor? We recommend that the flow restrictor should be replaced every time an RO membrane is replaced. Because over time, like RO membrane and filters, flow restrictors can also get choked because of scale build-up.
A quick and easy way to increase water pressure is to adjust the pressure-reducing valve, which can be found in your home, usually close to your water meter. If your pressure gauge reading was low, make slight adjustments to your regulator.
On average, water pressure regulator replacement costs $350 or between $250 and $450. You'll pay an additional $100 to $300 for after-hours, weekends, holidays, or projects with access issues. Also called a pressure-reducing valve, each valve costs $50 to $100 on average, but can hit $200 for most single-family homes.
Shower leaks can commonly occur in the joint between the shower tray and the walls. This could be due to: Movement of the shower tray. Sealant issues – if a poor adhesive was applied, or if there's mould in the sealant.
More often than not, a dripping showerhead is the result of worn or damaged inner seals. The rubber washers or O-rings in your shower act as a seal between your showerhead and shower hose, preventing water from leaking out. Over time, these wear down, and when they do, water starts to leak out.
Turn the vent fan on before you start your shower, and let it run for 20 minutes after you finish your shower. Installing a timer switch or humidity sensing fan is a good way to make sure you run the fan long enough to clear the air after a shower. Make sure the exhaust fan vents outside through a wall or roof.
For showers/tubs, look around the tub or shower for an access panel. It may be on the other side of the wall from the tub or shower. If it is not found behind an access panel, then it may be located under the floor in the basement or a ceiling access panel in the floor below.
Is there a water shut off valve for shower?
Some shower or bathtub shutoff valves may also be underneath the sink, but if they're not and you have a basement in your home, then check in the basement directly below the bathroom.

The innovative, WaterSense-certified shower head sets the bar with an unheard of standard flow rate of 0.625 GPM. This rate is one of the lowest in the industry, yet it still maintains the feel of a consistent stream of water.
Since 1992, a maximum of 2.5 GPM is the federally mandated flow rate for new shower heads. This means no more than 2.5 gallons of water should flow out each minute.
When it comes to Shower Heads, you'll typically find 2.5 GPM, 2.0 GPM, 1.8 GPM and 1.5 GPM. If you're looking for the most pressure, go for the 2.5 GPM Flow Rate, unless you are restricted because you reside in California, Colorado or New York. Again, this has been the Maximum Flow Rate since 1992.
Studies have shown that 1.8 gpm is the minimum flow rate to have a good enjoyable rinsing, so the common 1.75 gpm models, is somewhat good enough for a decent shower. To save water further and still have a full enjoyable rinsing experience.
Most low-flow showerheads have a rubber pressure-reducing valve (called a regulator) to maintain a lower pressure. You can increase the flow by simply taking it out. You could also consider enlarging the hole that allows water into your showerhead with a drill to increase the amount of water coming through.
Are there shower heads that increase water pressure? Yes. High-pressure shower heads increase water pressure either by decreasing the flow rate or using a compression chamber.
Efficient shower heads use at least 1.5gpm. Taking the same amount of time in the shower uses only 15 gallons of water. The water savings amount up to 65 gallons of water!
InvigoRain pressurized technology channels water throughout the whole showerhead, providing a powerful spray that is dispersed evenly for a more thorough rinse. Its 2.5-GPM max flow rate provides a steady stream of water, ensuring that all soap and shampoo is washed away with ease.
Because they're so much bigger than the average showerhead, but still provide the same amount of water (which can vary by water-saving mandate depending on where you live), it's just math: The same amount of water delivered across a bigger surface = less pressure. That's not the only drawback.
Are 2.5 gpm shower heads allowed in California?
Last week, the California Energy Commission approved new standards for showerheads that would reduce the amount of water flowing out of your shower to 2.0 gallons per minute, with a water pressure of 80 pounds per square inch. That is down from the state's previous requirements of 2.5 gallons per minute.
